The Use of Hydrogen Peroxide in Cleaning

图片
  While domestic and commercial cleaning share the same basic goal—cleaning—there are some distinctions between the two. The primary difference often lies in the equipment and materials used. Professional cleaners typically rely on high-powered, industrial-grade machines and chemicals that are unnecessary for routine home cleaning tasks.   However, you might be surprised to learn that many home cleaning methods and "hacks" are also employed by commercial cleaners. A classic example is the baking soda and white vinegar mixture, a staple in both domestic and commercial cleaning. Another versatile solution is hydrogen peroxide, which will be explored further below.   What Is Hydrogen Peroxide?   Hydrogen peroxide  is a versatile chemical compound with a wide range of uses. It is commonly found in personal care products such as toothpaste, mouthwash, and certain types of hair dye. Additionally, hydrogen peroxide is a staple in first aid antiseptics due to its disinf...

  What is MEG for PET?   MEG is the most common industrial diol which is used in manufacture of polyester fibre, fabrics and polyethylene terephthalate (PET) resin used for production of plastic bottles. Other industrial uses are as a coolant, heat transfer agent, antifreeze and a hydrate inhibitor in gas pipelines.   1. Understanding Monoethylene Glycol (MEG)   1.1 Definition and Chemical Properties   Monoethylene Glycol (MEG)  is a clear, colorless liquid with a sweet taste. Chemically, it's a diol, or a type of alcohol with two hydroxyl groups. MEG is produced from ethylene oxide through a process known as hydrolysis. Its primary characteristics include high solubility in water and low volatility, making it an essential compound in various industrial processes.   1.2 Production Process   MEG is typically manufactured through the reaction of ethylene oxide with water. This process involves the following steps:   - Ethylene Oxide Synthesis: ...
